Here’s a great move to work the muscles that run down each side of your body, from your lower ribs down. The weighted oblique twist will strengthen your obliques, which in turn will help fortify your core and lower back, improve your posture and help prevent injury from any bending or twisting movement. Plus, having firm obliques is the key to trimming your waistline.

Not sure if this move is for you? If you can roll over to the other side of the bed, and you’re comfortable balancing on a Swiss ball, then you’re ready for the weighted oblique twist. It’s that simple! Let’s begin:
Step 1: Sit on the ball, holding a dumbbell just under your chin. Walk your feet forward until your hips are slightly lower than your chest. Keep your abs tight and chin up. Turn to one side to begin the exercise.
Step 2: Slowly twist your torso to the other side through a count of 10.
Step 3: Hold and squeeze for 2 seconds at the maximum tension point.
Step 4: Then twist to the other side through a count of 10 seconds.
Step 5: Repeat three times without resting.
